About the Role

We are seeking experienced Frontend and UI Engineers to contribute to a project focused on developing challenging, verifiable coding tasks from visual materials.

In this role, you will transform screenshots, UI mockups, diagrams, and screen recordings of real workflows into structured coding tasks with clear requirements and objective success criteria. You will also provide working reference implementations and review tasks created by other contributors for technical accuracy and verifiability.

This opportunity is suited to frontend engineers and product or UI designers with hands-on development experience and a strong, publicly verifiable GitHub contribution history.

Key Responsibilities

• Design multi-step coding tasks based on screenshots, UI mockups, diagrams, and screen recordings of real workflows.

• Specify the code, application components, and artifacts involved in each task.

• Define expected application behavior and objective criteria for verifying successful completion.

• Develop working reference implementations that demonstrate the expected outcomes.

• Review tasks created by other contributors for technical accuracy, clarity, and verifiability.

• Identify and flag ambiguous or ungradable tasks rather than submitting tasks that cannot be objectively evaluated.

• Provide clear technical explanations and reproducible verification steps.

Required Qualifications

• A public GitHub profile demonstrating substantial, verifiable contributions through commits, merged pull requests, or maintained repositories. This is essential.

• Strong frontend engineering experience with React, TypeScript, or comparable technologies.

• Experience building and shipping complex interfaces and interactive applications.

• Ability to read, modify, debug, and validate production-level application code.

• Strong written English and the ability to explain expected behavior and reproducible testing procedures.

Preferred Qualifications

• Experience with UI engineering, graphics programming, SVG, or Canvas.

• Background in product design or UI design combined with hands-on frontend implementation.

• Experience with data labeling, AI evaluation, or rubric-based technical reviews.

• Experience developing objective evaluation criteria for software tasks.
